I believe the TWAW mantra is dangerous. Please ask your dd to read this.
- Medical
Medical staff need to know your sex when carrying out tests, lung function tests in particular are based on sex, race and height. If you input details as a woman when you are assessing a trans woman you may not pick up asthma or any reduced flow leading to a TW not being treated.
Smear tests, only records for 'female' trigger a automatic invitation to smear tests and mammograms. If medical records recorded sex then TW would be called for prostate tests and TM for smears, when you arrive you are called by your chosen name and treated as your chosen gender.
For medical professionals it also allows us to be more discrete eg we can book a trans person's appointment at the start or end of a clinic so a TW is not sitting in a waiting area with men and TM are not in a clinic with women. Not everyone minds but it's nice to offer the option.
Some of the cross sex hormones can cause things like brittle bones so a trans person with a broken bone needs to have the hormones assessed as well as 'just' fixing the broken bone. Peter Tatchell has criticized Drs asking for medical details as being transphobic for taking a full medical history when it is necessary.
- Individual rights
Not all TW believe they are women, Debbie Hayton is vocal that she can live as a woman, but she knows that the surgery and hormones just produce cosmetic changes, she doesn't have a cervix or a vagina, those cannot be created by any medical treatment.
Debbie has as much right to identify as a trans women who doesn't believe in the mantra TWAW and to say that TWANW as anyone else. Why should she be silenced? Surely acceptance is accepting trans people however they ID and allowing their stories to be heard.
- Alternative therapy
Some people detransition, their voices should also be heard. Medical / surgical transition is the right thing for some people and they should be supported down that path, but they should also be allowed to explore other routes. Someone with body dismorphia may benefit from counseling about acceptance of their body regardless of whether they choose the surgical route. TWAW stops people seeking alternative routes that might be better for them as an individual.
As a medical professional I encountered a TW on a semi regular basis. Let's call her Lucy.
Lucy had body dismorphia and had chosen the surgical route, she had top surgery but during her assessments for 'bottom' surgery it was discovered she had a heart condition that meant she could not have the bottom surgery. Lucy hated her body more than ever and would self harm, and that's when I would encounter her. This is many years ago and I still think about her, I hope anesthetics have got better and that she got her surgery eventually. TWAW is not a mantra that would help her, counselling might.
- Security of women.
Most TW do not have any surgery so retain male body strength, muscle max and sexual organs. A person with a penis should not be locked in a cell with a woman, particularly when the TW is a rapist.
- Assaults on women and children
We know abusers will abuse, they will go to great lengths to do so, training as teachers or priests, getting involved with refugee charities, volunteering etc. The current idea of self ID leaves a huge open door for abusers to step through. No these are not genuine tw / tm but there is no way to assess this so it is sensible to keep them out of places where women and children are vulnerable eg toilets, disabled toilets are all gender neutral and don't you dare tell me it is 'degrading' because if it is good for me as a disabled person then it is good enough for a trans person. It also allows for TM dealing with a period to have access to a space they can wash and change.
